Featured Reviews

All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services

The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

Offers performance control and cloud integration while supporting data management with granular flexibility

The scalability of NetApp Cloud Volumes ONTAP is interesting. We have thought about it, but we haven't used it. I think the scalability is something you scale up rather than respond to peak demand. It wouldn't help with outages either; the scaling is manual, and there are no processes we've used to automate that for unexpected scenarios. We like the scalability; it's enough for what we're planning to use, but we haven't used any advanced features. The standard platform is NetApp Cloud Volumes ONTAP, which is their cloud service. In fact, that's probably the most experience I have with NetApp. I've experienced it on-premise, but kind of secondhand.

Meets our customers' needs but they should move towards high-level scaling

I the product already has scalability features, but in terms of size maybe they could do more to work with parent storage and move to high-level scaling. That area, I feel, is a place where there could be some more options in this solution. It would be a way to improve the scalability in another direction, maybe options to scale out rather than just up. So far we have done very few installations. So maybe in the coming days, weeks and months, we would be able to come up with some additional features that are needed, but right now the product has the competitive features that our clients need.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The performance and the ever-growing maintenance are the most valuable features of this solution."

"I would highly recommend this solution; it has all the features we need and tests all the software solutions that are currently available and that will be available in the future."

"Cuts VM deployment down to seconds and cuts latency under MS with amazing performance and very stable operation with no worries about how much it can handle."

"The deduplication and compression rates are beyond impressive."

"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."

"The biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."

"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."

"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."

More Everpure FlashArray pros

"If you have a fair amount of experience with NetApp, you can work on it very easily."

"The fast recovery time objective with the ability to bring the environment back to production in case something happens."

"NetApp is a user-friendly solution, and I would recommend it to colleagues because of its user-friendliness for implementation and running your operations."

"The ease of use in terms of how the product works is valuable. We are able to work with it and deploy the storage that we need."

"Cloud Volumes ONTAP is NetApp; it's the same technology which is where the efficiency really is, and it's much more efficient than using a third-party solution."

"One of the features of this tool is the ease of use, in addition to the control access and the dynamics with which it is structured."

"The solution's high-availability features are cost-effective for us because we are able to use the cloud benefits to reduce the cost of DR."

"It is a good system; it is very stable as far as what I've been using with it, and I find that support from it is really good as well."

More NetApp Cloud Volumes ONTAP pros

"Automatic rebalancing is the feature saving administration time, and also auto rebuilding."

"The ScaleIO UI: EMC has been working with storage for a long time; therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth, and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects."

"Comparing other products that are competing with Dell EMC (Enhanced Memory Controller), Dell seems to us to always come out on the high-side."

"We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms."

Cons

"The integration capabilities could be improved."

"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."

"CIFS and SMB Shares cannot be mounted directly."

"The solution could improve by having a multi-tenant feature."

"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."

"In the next release of the solution I would like to see Vormetric native block encryption."

"The scalability of the solution is not as good as it probably could be."

"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."

More Everpure FlashArray cons

"I would like some more performance matrices to know what it is doing."

"Some of the licensing is a little kludgy. We just created an HA environment in Azure and their licensing for SVMs per node is a little kludgy. They're working on it right now."

"I have used technical support and it's mediocre."

"The support is good in general but the initial, frontline support could be improved."

"We have customers that are still using IBM mainframes and that very old SNA architecture from IBM. There are questions about how you interconnect the data on the mainframe side... But I don't know if it's worth it for NetApp to invest in developing products to include mainframes for a few customers."

"I would like this solution to be brought to all the three major players. Right now it's supported only on AWS and Azure. They should bring it to Google as well, because we would like to have flexibility in choosing the underlying cloud storage provider."

"I would like some more performance matrices to know what it is doing. It has some matrices inherent to the Cloud Volumes ONTAP. But inside Cloud Manager, it would also be nice to see. You can have a little Snapshot, then drill down if you go a little deeper."

"It needs better reporting. Right now, we had to put everything one to the other just to figure out what could be the issue."

More NetApp Cloud Volumes ONTAP cons

"It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc."

"I think ScaleIO already has some features for scalability as it is part of the reason for the product, but in terms of size, maybe they should try to address parent storage."

"There is room for improvement in the area of horizontal scaling."

"If they could introduce a write cache feature, the product would be perfect overall."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO."

Pricing and Cost Advice

"Pure Storage FlashArray is expensive."

"There are no fees for licensing. The hardware is paid for only once."

"We do not incur additional costs beyond the licensing fee."

"For us, as the customer, it reduced the price of the management."

"Price is about the only thing that's wrong with it. A little bit better pricing would be great."

"It's a good price point and it's a solid product for the price."

"It's expensive, but you get what you pay for."

"We have an Evergreen Storage subscription, which I think is a great feature."

More Everpure FlashArray pricing and cost advice

"It is expensive. There are no costs in addition to their standard licensing fees."

"The deal with the seller was acceptable; the pricing is reasonable."

"The solution's pricing is reasonable."

"We find the pricing to be favorable due to the educational sector we belong to."

"It is not a cheap solution because we need to pay for the license and pay for Azure resources as well."

"Compared to other storage vendors, NetApp, is not always able to compete with their pricing. Yet, we acknowledge the ease of use ONTAP brings with the AWS integration."

"The pricing of this solution is definitely higher than what the typical Azure Files and AWS solutions charge, but given the features and the stability NetApp has provided, we are okay with it. We are not complaining about the pricing."

"The standard pricing is online. Pricing depends. If you're using the PayGo model, then it's just the normal costs on the Microsoft page. If you're using Bring Your Own License, which is what we're doing, then you get with your sales contact at NetApp and start figuring out what price is the best, in the end, for your company."
